ACS took over my pharmacy that closed and sent out...

ACS took over my pharmacy that closed and sent out a letter stating it would be a "seamless transition". It has been anything but. They claim to have not received any records from my old pharmacy. I have called 5 times with the information and each time I call ACS says, "We don't have any notes on you." Then they claim they have left multiple messages for my doctor's office to obtain the prescription. My doctor's nurse tells me no one ever called. My nurse is now switching all her patients to a different pharmacy. ACS's loss...the prescription I use is really expensive!
